Q1. A 59-g ice cube at 0°C is heated until 52 g has become water at 100°C and 7.0 g has become steam at 100°C. How much energy was added to accomplish the transformation?
Q2. Consider two dimensional simple triangular lattice for free electron metal with two electrons per atom. Assume the lattice constant is a, find the areas electron and hole pockets that are formed in the second and first Brillouin zones respectively. Find the shapes electron and whole Fermi surfaces in the reduced zone, obtained throughout translation by a reciprocal lattice vector.
